Description

Technical Field

[0001] The utility model relates to the field of manufacturing of plate condensers, and particularly relates to a spraying device for plate condensers. Background Art

[0002] In a plate condenser, a spraying device is needed to cool down a condensation component (a heat exchange component), so that a refrigerant can achieve the effect of condensation phase change. The existing spraying devices usually adopt a plurality of horizontally connected water spraying pipes, and a plurality of water spraying orifices are arranged at the bottom of the water spraying pipes, and water flows down through the water spraying orifices to cool down the condensation component. During the actual operation of the condenser, dirt residues are mixed in the water, and the residues will enter the water spraying pipes of the spraying device from the water collecting tank along with the water. Since the diameter of the water spraying orifices is small, the residues will gradually block the water spraying orifices, resulting in uneven water spraying and affecting the cooling effect; when the water spraying orifices are blocked to a certain extent, disassembly and cleaning must be carried out. Especially in summer, since the plate condenser is placed outdoors, mosquito residues are easily accumulated in the water collecting tank, making the water spraying orifices easily blocked, and frequent cleaning is required, which greatly affects the working efficiency of the plate condenser and wastes manpower and material resources. Summary of the Invention

Support rings are sleeved at both ends of the water spraying pipes. The two ends of the cover plate are respectively connected to the support rings at both ends of the water spraying pipes. A cavity for water flow to pass through is formed between the water spraying orifices and the cover plate. During the process of water flowing through the water spraying pipes, the residues will sink due to the action of gravity, and then cool and circulate along with the water flow, and will not block the water spraying orifices. Even if a small amount of residues are blocked, it will not affect the cooling effect of the condenser. The water sprayed from the water spraying orifices is dispersed after being blocked by the cover plate, making the water spraying cooling effect more uniform, and can improve the working efficiency of the condenser; the subsequent small amount of residues blocking the water spraying orifices will be sprayed out with the water from the water spraying orifices or sink and flow out with the water in the water spraying pipes, realizing self-cleaning of the residues; it can reduce the blockage of the water spraying orifices by residues, reduce the number of disassembly and cleaning, and reduce the waste of manpower and material resources.
